I did this fun little hike with the two dogs Koa and Uila (pronounced Wee-la) I was sitting and a local MeetUp group, the Kauai Adventure Club. This is a great hike in the Kapahi neighbor just off of Kapahi Road:
Parking is parallel and off-street, on the opposite side from the houses:
You can find the trailhead at the yellow gate marking a public access dirt road:
The trail begins quite broadly but quickly narrows and you feel like you are going deep into the heart of the jungle:
Soon you come across the lush Kapa'a stream running through the forest.
And in less than a mile you arrive to the first of two falls:
Some people, like our unofficial guide Manfred who has been living here for 30 years, swan dive off the far side of the falls (but only after checking for rocks and debris below first, of course!).
The next section of the trail goes through some pristine forest of what I believe are called wiliwili trees, with a lush tropical vine growing on them I see everywhere on Kaua'i but can't remember the name! ...It reminds me of kudzu.
A little while longer and you come across some larger falls. In high water, the falls apparently go all the way across the stone rim!
There is a trail around to the right that leads down a fairly steep but doable trail to the bottom, where you are richly rewarded with a nice picnic and swimming area, complete with a rope swing!
All in all, a great, short, refreshing hike not ten minutes from where we live!
